Yggdrasil and AvatarUX have teamed up to fight hordes of the undead in their latest launch Zombie aPOPalypse™.

The reels are set in a world where zombies run amok, and players look to generate big wins in the 5×4, pays-both-ways title that boasts a max win of 20,000x.

The MultiPop™ mechanic works by locking a multiplier to a cell for every win that occurs. When winning symbols are replaced, the multiplier stays on the reels, increasing for each consecutive win it is part of, to totals of up to 5x in base play.

Infectious multipliers can also appear when a max multiplier is reached during base game. When this occurs, anything from four to 12 cells are upgraded with an additional 1x multiplier.

Three or more brain scatter symbols will trigger the Free Spins mode, where the grid is increased to 5×5 in size, and locked for the duration. The max a multiplier can reach in this round is 10x, and if all reels are filled with multipliers, an extra two spins are awarded.

Before players enter the bonus mode, they can face the gamble wheel, where they can risk potentially winning even more Free Spins. In certain jurisdictions, players can progress directly to the bonus with one of two purchase buy options.

Zombie aPOPalypse is powered by GATI, Yggdrasil’s state-of-the-art technology enabling partners to employ the preconfigured, regulation-ready, standardised development toolkit to consistently produce cutting-edge content followed by rapid distribution.

Stuart McCarthy, Head of Product & Programs at Yggdrasil, said: “AvatarUX continues to create innovative, exciting content and they have pushed the envelope again with Zombie aPOPalypse which introduces the new MultiPop™ mechanic.

“The thrilling game sees a new, frightening theme added to its portfolio, and we’re very happy to work with such a forward-thinking brand.”

Nicola Longmuir, CEO at AvatarUX, said: “We’re incredibly excited to launch Zombie aPOPalypse, where we yet again evolve our portfolio with new mechanics and features.

“We are working hard to further expand our games portfolio with innovative and entertaining titles and with big multipliers able to land on every spin, and a pays-both-ways mechanic, we feel this game has plenty to get players excited about.”
